ing oppositely disposed notches 9 cut in its edges at regular intervals,forming a ratchet. The notches on one edge are spaced longitudinally onbar 8, mid-distant from the notches on the opposite edge. Looselymounted on bar 8 is keeper 10, having pivotally secured thereto, rockerlever 11composed of two sections spaced apart the width of bar 8 andpreferably riveted together. A pair of reversely d'sposed pawls 12 arepivoted to rocker lever 11 between the two sections thereof andarepositioned at opposite sides of bar 8 to alternately engage thenotches 9 thereon.

A framelS of substantially bow or U- shape is bolted to bar thereoftowards which notches 9 point. Bow 13 is preferably composed of twoparallel spaced bars connected together by rivthrough spacing thimbles.A bar 14: adapted to form a post abutting shoulder is secured at one endto bow 13 and at its other end to one end of frame member 8, said barbeing disposed substantially at right angles to frame member 8. lVireguides 15 are bolted to the outer end of bow 13 and frame member 8 onthe upper surfaces thereof, in substantial alignment 8 adjacent the endtherewith. Guides 15 maybe made circular v in shape with a flat boltingsurface and an opening for the insertion and removal of the wires.Clamps 16 and 17 are provided composed of levers 16 and 17,respectively, with inner notched shoulders thereon and clamp jaw members16 and 17 respectively, said levers and members being connected togetherby pivots. Said jaw members have lateral ledges or shoulders cooperatingwith thenotched shoulder portions on said levers. Clamp 16 is secured tothe outer unattached end of bow 13 by having its jaw members boltedthereto, and clamp 17 to one section of the rocker lever 11 intermediatethe two pawls 12, said clamp being secured similar to clamp 16.

The operation of the hen the device is used wire, the same is disposed7, the shoulder 1 1 abutting against the post or other base ofresistance D The rocker lever 11, keeper 10 and pawls 12 are pusheddevice is as follows: to stretch but one as shownin Fig.

to a position adjacent the bow 13 by releasing the pawls 12 fromengagement with notches 9. This may readily be done by grasping thehandleportions of the pawls and moving them together. Wire E is thenplaced through the opening in the guide 15 situated at the outer end ofbow 18. A portion of the wire is then inserted between the lever 17 andthe jaw 17 of open clamp 17. The clamp lever 17 is then turned upward tothe dotted position shown in Fig. 6 and the Wire is then Secure.Shoulder 14: is placed against a base of reaction such as a post D,which will fit within the bow 13. The lever 11 will then be rocked, thepawls 12 alternately engaging with the notches 9, said lever being movedalong frame 8 to draw the clamp secured end of the wire away from theshoulder 14 towards the free end of bar 8. As the rocker lever 11 hasconsiderable length, there will be suiiicient power exerted, Without anygreat effort, to give the wire B any desired tension. Because of bow 13and the wire B, running across the open side thereof, there will be notendency for the device to slip away from or off of the base ofresistance. The wire can then be secured to the object, which is used asa base of resistance, such as the post D, or to any other object underthe desired tension. The clamp 17 can then be released and the wirestretcher removed.

when the device is used for stretching and splicing two wires extendingin opposite directions, or for stretching and splicing a broken wire,the device is disposed as shown in Fig. 1. The wires B and C, to betensio-ned and spliced, are anchored at some suitable member such aspost A. No base of reaction is required against which the stretcher andsplicer must act. The wire B is led through guide 15 adjacent the bow 13and is secured by clamp 17. l/Vire G is then placed through guide 15 atthe outer end of frame member 8 and, if long enough, is placed betweenthe jaws ofclamp 16 and secured. If wire C is not of sufiicient lengthto extend to clamp 16, as would most likely be the case, when it isdesired to splice a broken wire under tension, an auxiliary piece ofwire is connected thereto of sutlicient length to reach clamp 16 and itis securely engaged thereby. The lever 11 is then rocked as before todraw the clamp secured ends of wire B away from the bow 13. The tensionexerted on wires C and B will be equalized and both wires will quicklyand easily be brought up to the desired tension. The two wires extendacross the bow l3 and can then be grasped while under tension withsuitable pliers or other means, and held. Clamps 16and 17 are thenreleased and the wire stretcher removed. The two wires can then beeasily spliced under tension by the pliers or by means of a splicingtool.

The device has been amply demonstrated in actual practice and has beenfound very etlicient for the purposes specified.

It will be readily seen that an exceedingly simple and eflicient wirestretcher and splicer has been provided, which can be'easily andquickly'operated by one man to hold wire at any desired tension forfastening or splicing.

It is, of course, understood that various changes in the forms anddetails of the invention may be made without departing from the scope ofapplicants invention, which, generally stated, consists of the mattershown and described and set forth in the appended claims.

What is claimed is:

1. A wire stretcher gated frame, a wire positioning bow fixed at one endthereof, a shoulder fixedly secured to the inner side of said bow andthe bow end of said frame, said shoulder being adaptcomprising an elonedto abut against a fixed base of resistance,

and a tensioning device movable on said frame away from said, shoulder,having means for releasably securing a portion of the anchored wire sothat said wire will extend across the open side of said bow.

2. A wire stretcher and splicer, adapted to be used with two oppositelydisposed anchored wires, having in combination an elongated frame havinga bow at one end, across the open side of which said wires run, clampingmeans for securing the free end of one of said wires at the outer end ofsaid bow, a tensioning device movably mounted on the intermediateportion of said frame and clamping means secured to said tensioningdevice for securing the free end of the other of said wires, wherebysaid wires can be tensioned and held across said bow for splicing.

A wire stretcher comprising an elongated frame, a bow rigidly fixed atits inner side to one end of said frame, the open side of said bow beingalong the line of said frame, a wire holding clamp secured at the outerend of said bow, a wire tensioning means movable on said frame away fromsaid bow, a wire tensioning clamp secured to said means, each of saidclamps being adapted to hold an end of a wire so that the two wires willextend across the open end of'said bow, whereby the wires may beconveniently spliced within the outline of said bow after beingtensioned.

In testimony whereof we afiix our signatures.
